CURTAINWINDOW INSTALLATION.

Application filed January 14, 1925. Serial No. 2,289.

This invention aims to provide an improved curtain window installation, and improved frame members for the same.

In the drawings, which illustrate a pre ferred embodiment of my invention Figure 1 is a rear elevationview of the installation as applied to a flexible curtain;

Fig. 2 is an enlarged section on the line 22 of Fig. 1, the center part being broken away s Fig. 3 is an elevation view of the prong- ;n'esenting frame member;

Fig. 9 isa section similar to Fig. 8, showing the frame parts just prior to bending the prong-concealing flange of the removable :end before and after it is clenched in plate;-

Figl 17 is an enlarged section on the line 1717 of Fig. 15, showing a fabric-gripping spur; and y Fig. 18 is an enlarged section on. the line 1818-of Fig. 1, showing an attaching screw in elevation.

Referring to the drawings, I have shown a curtainwindow installation which is particularly, though not exclusively, useful as a curtain window installation for automobile s.

The installation includes a curtain fabric" 1, a glass-2 and a plurality of metal frame parts secured to the curtain for holding the glass in place relative thereto. In installations of the kind illustrated, it is particularly helpful to secure as many of the metal frame parts permanently to the curtain fabric as possible. To this end, IQhave provided one of the frame parts with a removable end portion, which may be removed from the installation independently of the rest of the frame parts, thereby permitting the glass to be slid out of engagement with therest of the frame," as more fully hereinafter described.

The metal frame parts include a prongpresenting frame unit 3 located at the outer face of the curtain I and a glass-holding prong-receiving frame member 4 secured to the inner face of the curtain, as illustrated in Fig. 2. The pong-presenting frame unit 3 includes an outer frame part 5 (Figs'Q and 3) presenting at the exposed face thereof acentral stiffening rib 6, and an inner frame part or insert .7. This inner frame part is preferably, as illustrated in Fig. 5, formed from sheet metal and comprises four separate pieces secured to the outer frame part 5 by flanges 8 and .8 extending inwardly over the insert 7 from the inner and outer edges of the outer frame member 5. These flanges are cut away at the corners of the frame to permit bending thereof at the straight sides of the frames. -The flange 8 extending from the inner edge of the frame part 5 presents, at its free edge, a plurality of outwardly extending prongs 9 for securing the frame unit 3 to the curtain 1.

The inserts are important inasmuch as they strengthen the frame part 5, backsupport the attaching prongs 9 and present,

between the flanges 8 and 8 at the corners v of the frame unit 3, attaching prongs 10 and screw-receiving portions'll, as best illustrated in Figs. 2, 13 and 14, the purposes of which are hereinafter.described.

Figs. 1 through 14 include sections which illustrate the method of assembling the frame unit The piecesof the insert are placed between the upstanding flanges 7 and 8, as illustratedin Fig. 10, and the flanges are then bent inwardly, Fig. 11,

' tively wide fabric-gripping surface 12 in which: are provided a. plurality of notch-ed prong receiving slots 13 (F igs. 6 and 7 a normally slightly inwardly bentflange 14 at the outer edge of the frame and an angular portion 15 at the inner edge of the frame providing a glass-receiving recess, as illus trated in Figs. 2, 6 and. 8. One end 16 of the glassholding frame part is Separated from the rest of the frame and this end includes the rounded corners at that end thereof as illustrated in Figs. 1, 6 and15'. This frame part 4 is pressed from a single sheet of metal. as illustrated in Figs. 15 through 17 and the flange 14 extends outwardly therefrom (Fig. 16). The removable portion 16 is cut off from the rest of the frame 4 and the flange 14 is bent inwardly against the portion 12, While the flange 14 of the remainder of the frame is bent slightlyinwardly, as illustrated in Fig. 17. Thus the frame parts are made ready for assembly to the curtain fabric 1.

Assembly of the installation is as follows ;first the frame unit 8 is placed upon a table or bench, the prongs projecting upwardly therefrom. The curtain fabric 1 is then placed over the frame and the prongs pressed through the fabric. The frame part 4, except the removable end, is then placed over the curtain so that the prongs 9 engage the slots 13 and so that the attaching prongs 10, presented by the inserts 7 engage the slots 13 at the rounded corners. The flanges 14 are thereafter bent downwardly and these flanges engage and bend the prongs 9 against the upper face of the fabric-engaging portion 12 of the frame part4 (Fig. 2). The prongs 10, which are exposed at the corners, may then be pressed into engagement with theframe part 4. Thus the frame members are permanently secured to the curtain fabric 1 and need not be separated therefrom when the glass 2 is being changed. A firm grip on the curtain fabric 1 between the frame members 3 and 4 is provided by forming a plurality of spurs 20 (Figs. 6 and 17), which grip the fabric. The prongs 9,

' which are located at that end of the frame which is removable, are bent against the curtain fabric 1 (Fig. 2) and the. glass may then he slid into the groove/provided be tween the frame parts 3 and 4, the fabric providing a cushion from one side of the.

of the slot as illustrated in Figs. 7, 8 and 9.

Thus the assembly of the frame parts is greatly simplified and much time is saved. Slightly bent prongs (Fig.8) are automatically straightened and guided into thesl-ots (Fig. 9-) by these notches.

While I have shown and described apref'crred embodiment of my invention, it will be understood that changes involving omission, substitution, alterationand even rcversal of parts may be made without departing from the scope of my invention,

which is best defined in the following-claims.
